It carries 65 A at 480 V and 52 A at 600 V, which means it handles moderate-to-heavy motor duty up to those levels without derating the main poles. That gives panel builders room to fit it into tight layouts without worrying about orientation limits.
Clearances and integration
Those are the minimum air gaps around the contactor for heat dissipation and arc containment. The auxiliary switch is built in (yes), and the main contact count is 18 normally open, 1 normally closed — that's a 3-pole plus auxiliary configuration typical for motor starting with feedback. Wire termination accepts 2x (0.5 to 2.5 mm²) solid or stranded, spring-cage style, so no ferrule needed for stranded unless your shop standard requires it.
Environmental and duty ratings
The maximum switching rate at AC-4 duty (plugging/inching) is 200 operations per hour — useful to know if you're cycling a reversing starter hard.
